    Science objectives/activities planned:
The objectives of the Hilton/Brown segment of the cruise are two-fold. First, the primary objective is to test a series of instruments on the diffuse flow site on Endeavor Ridge including the following four instrument packages during the course of 3-4 dives on Endeavor: 1) An optical flow meter and a CAT (Chemical and Aqueous Transport) meter (2 separate instruments) to measure fluid fluxes in diffuse outflow zones of medium-to-low temperature vent sites, and collect these fluids and dissolved gases. Secondly, if it is ready in time we plan to deploy the Mass SURFER (McMurtery, Hawaii) - a miniaturized mass spectrometer-based sampling system, which will produce a continuous record of vent chemistry. Deployment of two instruments in close proximity to one another is necessary for the development of and inter-comparison between the two instrument packages. As a means to check the integrity of He-C results obtained from the Cu-coils, we plan to also obtain vent fluids using the major water samplers plus any submarine glasses in the vicinity of the vent sites.

Subsequently, if time permits we wish to undertake exploratory investigation (2 days max) of the fault scarp at the deformation front in the region of the intersection of the Nootka fault system and the deformation in front of the Cascadia wedge (just off Vancouver Island). The principal objective here would be to explore, photograph, and sample along the fault scarp in order to find cold seep site and evidence for the timing of faulting activity etc along it. This would occur dependent on completion of the necessary instrument test deployments (i.e. weather may be a factor).
